A laptop can be powered by either an AC power adaptor or a laptop battery. Laptop batteries typically can charge a laptop for two to four hours, depending on the size and type of battery and the applications being used by the laptop user. Once the battery dies or has drained, it can no longer power the laptop and the laptop must be connected to a power source to be turned on. If the battery will not charge, there is no safe way to revive it and it will need to be replaced.

Skill level:


  1. 1

    Plug the power adaptor jack into the power adaptor outlet. The outlet is located on the side of most brands and models of laptops.

  2. 2

    Insert the other end of the power adaptor into a power source. An electrical socket is the most common type of power source. Depending on the type of power adaptor cord, a computer USB port or a vehicle cigarette lighter outlet can provide power as well.

  3. 3

    Allow the battery to fully charge. Laptops have a battery indicator light, located on the front of the laptop, that turns on to indicate that the battery is charging. Depending on the size and type of battery, it typically takes four to eight hours to fully charge a drained or dead battery.
